Osaka University researchers studied the effect of the “attitudes” of a semi-autonomous telepresence robot on its human operator. They found that when a person controlled only a part of the body of a semi-autonomous robot, its expressed opinions affected him or her. This work may help assist in the development of new semi-autonomous robots to perform labor more efficiently.

A collaborative research group has discovered electrical brain-wave patterns given off during social interactions in mice. They also observed that mice showing signs of stress, depression, or autism lacked these brain waves. The results reveal more about the mechanics underlying brain activity when socializing.
Structural features of SiO2 glass under pressure.
27 Jun 2022
Understanding the structural origin of the anomalous properties of SiO2 liquid and glass is of great interest in a wide range of scientific fields. The fraction of the S state with tetrahedral symmetry structure is considered to be the controlling parameter of the anomalous properties of SiO2 liquid in theoretical studies. However, it has not been well identified in experiments. In this work, we find experimental evidence of tetrahedral symmetry breaking in SiO2 glass under pressure.

Researchers from Osaka University have found that infection with SARS-CoV-2 activates the expression of IRF1, a key regulator of insulin/IGF signaling in multiple tissues, leading to disruption of blood sugar metabolism and, in some cases, new onset of diabetes. Treating infected cells with hormonal factors that decreased IRF1 expression enhanced insulin/IGF signaling, suggesting that this approach could be used to mitigate some of the more severe side effects of COVID-19 in the future.

Osaka University researchers develop a novel microfluidic chip that can detect very small concentrations of dissolved contaminants using just 100-picoliter sized samples. By using a terahertz point source, the detection area can be made very small. This work may lead to lab-on-a-chip technology for environmental and health care monitoring.

An international team led by Osaka University used experimental measurements and theoretical modeling to better understand the shape formed by the protons and neutrons in the atomic nucleus of calcium-40. They found that destructive interference affects the mixture of elongated and spherical states. This research may help shed light on the reasons for the relative stability of atomic nuclei and how they are formed.

Osaka Metropolitan University scientists detected, for the first time, collective resonance at remarkably high and broad frequency bands. In a magnetic superstructure called a chiral spin soliton lattice (CSL), they found that resonance could occur at such frequencies with small changes in magnetic field strength. The findings suggest CSL-hosting chiral helimagnets as promising materials for future communication technologies.

Commercially available transparent face masks allow for the perception of facial expressions while suppressing the dispersion of respiratory droplets that spread the SARS-CoV-2 virus, and thus have a clear advantage over surgical face masks.
Nano-sized electrostatic atomized water particles destroy SARS-CoV-2 envelope, protein, and RNA
17 Jun 2022
A research group led by Osaka Metropolitan University and Panasonic Corporation Living Appliances and Solutions Company discovered how nano-sized electrostatic atomized water particles disinfect SARS-CoV-2. The nano-sized electrostatic atomized water particles developed by Panasonic Corporation have an electron rich nano-sized water shell that contains reactive oxygen species. The researchers showed that the water particles damage the viral envelope, protein, and RNA. They also revealed that the damaged virus did not bind to host cells. These phenomena are considered the main inactivation mechanism of the nano-sized electrostatic atomized water particles on SARS-CoV-2.
Balances depict pentacene’s photostability
17 Jun 2022
A research group led by Professor Yoshio Teki of the Osaka Metropolitan University Graduate School of Engineering has succeeded in developing a new pentacene derivative that is more than 100 times more photostable than TIPS-pentacene, a photostable pentacene derivative. Additionally, the team has further clarified the ultrafast excited state dynamics in this system. In the pentacene moiety of this system, we were able to demonstrate that the transition from the excited singlet state to the excited triplet state occurs ultrafast in the time region of a 10-13 seconds. In purely organic materials without heavy atoms such as rare metals, such intersystem crossing usually occurs on time scales longer than 10-9 seconds. The empirical results of this study are expected to be applied as a method for stabilizing and developing light-unstable materials in the future.

Potential of a novel therapeutic strategy for rheumatoid arthritis by UHRF1 stabilization We identified an epigenetic regulator UHRF1 that suppresses various pathogeneses in rheumatoid arthritis. The UHRF1 expression level in synovium showed a negative correlation with the severity of pathogenesis in patients with rheumatoid arthritis and mouse arthritis models. In addition, stabilization of the UHRF1 expression achieved improvement of the arthritis pathology. Our results indicate that the stabilization of the UHRF1 protein is a potential therapeutic strategy for rheumatoid arthritis patients.
